    <p> An HTTP and WebSockets server.
 <p>
 You receive HTTP requests by providing a <a href='../../../../../io/vertx/groovy/core/http/HttpServer.html#requestHandler' title='HttpServer.requestHandler'>HttpServer.requestHandler</a>. As requests arrive on the server the handler
 will be called with the requests.
 <p>
 You receive WebSockets by providing a <a href='../../../../../io/vertx/groovy/core/http/HttpServer.html#websocketHandler' title='HttpServer.websocketHandler'>HttpServer.websocketHandler</a>. As WebSocket connections arrive on the server, the
 WebSocket is passed to the handler.
